Install Docker in Google Colab!

install_docker_in_colab.sh

# First let's update all the packages to the latest ones with the following command
sudo apt update -qq

# Now we want to install some prerequisite packages which will let us use HTTPS over apt
sudo apt install apt-transport-https ca-certificates curl software-properties-common -qq

# After that we will add the GPG key for the official Docker repository to the system
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

# We will add the Docker repository to our APT sources
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"

# Next let's update the package database with our newly added Docker package repo
sudo apt update -qq

# Finally lets install docker with the below command
sudo apt install docker-ce

# Lets check that docker is running
docker

# Originally, we did the following: (but doesn't work in Colab...)
# sudo systemctl status docker

# The output should be similar to this snippet below
# ● docker.service - Docker Application Container Engine
#    Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
#    Active: active (running) since Tue 2019-01-01 19:22:114 UTC; 1min 25s ago
#      Docs: https://docs.docker.com
#  Main PID: 10096 (dockerd)
#     Tasks: 16
#    CGroup: /system.slice/docker.service
#            ├─10096 /usr/bin/dockerd -H fd://
#            └─10113 docker-containerd --config /var/run/docker/containerd/containerd.toml

# And now that everything is good, you should be able to do:

# docker run -it -p 8888:8888 gcr.io/tensorflow/tensorflow

Thanks for the efforts, but it doesn't seem to work for me.

Also based on this answer, Google doesn't support Docker and they don't plan to.

Can you give an example of a piece of code that run successfully on Colab using Docker.

Like here, it does seems to work on Colab

sudo dockerd

failed to start daemon: Error initializing network controller: error obtaining controller instance: failed to create NAT chain DOCKER: iptables failed: iptables -t nat -N DOCKER: iptables v1.6.1: can't initialize iptables table `nat': Permission denied (you must be root)
Perhaps iptables or your kernel needs to be upgraded

Wow thats worked for me just in an one shot. Thanks!!

It works for me, thank you so much!

I could not get it working in Colab
docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?. See 'docker run --help'.

It's not supported by Google officially.
googlecolab/colabtools#299

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

It works for me with Google Colab Pro and GPU Runtime

sudo dockerd

failed to start daemon: Error initializing network controller: error obtaining controller instance: failed to create NAT chain DOCKER: iptables failed: iptables -t nat -N DOCKER: iptables v1.6.1: can't initialize iptables table `nat': Permission denied (you must be root) Perhaps iptables or your kernel needs to be upgraded

same here

Apparently (at least the free) Colab runs in docker already:

Docker in docker requires some host container configurations to allow this.

This works for me...

installing docker:
!apt-get -qq install docker.io

running desired docker command (docker --version):

%%shell
set -x
dockerd -b none --iptables=0 -l warn &
for i in $(seq 5); do [ ! -S "/var/run/docker.sock" ] && sleep 2 || break; done
docker --version
kill $(jobs -p)

Are you on Google Colab, or running colab locally?

Google Colab

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

yeah, me too. Can anyone who can run successfully show me their script?

docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

I also met with the same problem.

docker: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?.
How to do?

Thanks a lot

Hi, I found a solution for this. Check out https://github.com/indigo-dc/udocker. It's working perfectly in the free version of Google Colab.

• Installation:

%%shell
pip install udocker
udocker --allow-root install

• Sample usage:

udocker --allow-root run -p 127.0.0.1:8081:8081 -v -e TELEGRAM_API_ID=#### -e TELEGRAM_API_HASH=#### -e TELEGRAM_LOCAL=1 aiogram/telegram-bot-api:latest

Cheers!

Thank you to @musahi0128, your solution worked for me.

@musahi0128 works perfectly!

Tested it with
!udocker --allow-root run hello-world

and checking for the running container with
!udocker --allow-root ps

!pip install udocker
!udocker --allow-root install
!udocker --allow-root run scrapinghub/splash

Requirement already satisfied: udocker in /usr/local/lib/python3.10/dist-packages (1.3.10)
Warning: this container exposes TCP/IP ports
Error: invalid syntax for user splash:splash

!pip install udocker
!udocker --allow-root install
!udocker --allow-root run scrapinghub/splash

Requirement already satisfied: udocker in /usr/local/lib/python3.10/dist-packages (1.3.10) Warning: this container exposes TCP/IP ports Error: invalid syntax for user splash:splash

Do you have the Dockerfile for that? It looks to me the error comes from within the container

@musahi0128 I am using https://github.com/scrapy-plugins/scrapy-splash#installation
